re: Another F-250 Thread - Used 2003 King Ranch with 6.0L

Stay away from the 'early' 6.0L or as we call them 'sick-O.

Go with a 7.3L if all possible BUT they are hard to find.

If you do go with a 6.0L engine, buy as cheap as possible. You will have to spend about $5-6K just to get it back to good.

Usually you are going to have change out the FICM(Fuel Injection Control Module, about $550).
HOP(High Oil Pressure pump, about $600).
Fuel Injectors(8 injectors will run about $1800).

Go back with an oil cooler replace kit($300).

You may have to redo the head-gaskets, go with ARP stud kit(around $500),and go with back with OE headgaskets(about $175 per side), stay away from the after-market crap like Black Oynx(they are useless).

Plus go with a EGR delete kit(around $150).


BTW, get a good Ford DIESEL mechanic to do the work.

Stay away from the jake-leg mechanics who worked on a diesel 5 years ago. He will most likely screw-up your engine.
The diesels, after 2003, are a brand-new ball game
